Abstract

La présente invention concerne un procédé d'amélioration de la cinétique de lixiviation d'un métal et de la récupération lors de la lixiviation atmosphérique ou sensiblement atmosphérique d'un sulfure métallique. Dans certains modes de réalisation, le procédé peut comprendre l'étape de traitement d'un concentré de sulfure métallique dans un circuit d'activation réductrice (220) qui fonctionne à un premier potentiel redox, pour produire un concentré de sulfure métallique activé par réduction. Le procédé peut en outre comprendre l'étape subséquente consistant à traiter le concentré de sulfure métallique activé dans un circuit de lixiviation oxydante (240) pour extraire des métaux de valeur. Dans certains modes de réalisation de la présente invention, des étapes d'activation réductrice et/ou des étapes de dissolution oxydante peuvent faire appel à un traitement mécano-chimique et/ou physico-chimique des particules ou de leurs agglomérats. Une activation réductrice peut être effectuée avant des opérations de lixiviation en tas ou de bio-lixiviation pour améliorer l'extraction des métaux. La présente invention concerne en outre la mise en œuvre des procédés décrits ci-dessus.
